The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
Compare how charge carriers move in a conductive material and explain how this relates to the Hall effect. In 1879, E.H. Hall devised an experiment that can be used to identify the sign of the predominant charge carriers in a conducting material.
11 sie 2024 · The Hall effect occurs when a magnetic field is applied at a right angle to an electric current flowing through a conductor. As a result, a voltage is created across the conductor, perpendicular to both the electric current and the magnetic field.
Learn how a magnetic field produces a transverse voltage in a conductor with moving charge carriers, called the Hall effect. Explore the formula, the Hall probe, and the applications of the Hall effect in different materials.
The Hall effect is used today as a research tool to probe the movement of charges, their drift velocities and densities, and so on, in materials. In 1980, it was discovered that the Hall effect is quantized, an example of quantum behavior in a macroscopic object.
Hall effect devices are direct energy conversion devices that convert energy from a magnetic field to electricity. The physics behind these devices is described by the Lorentz force equation.
18 wrz 2024 · metallic conduction. Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall.
